Mono Send Source Panning Issue

tremblap · 12-20-2013, 05:25 AM

Hello

I think I have found another bug, but after searching the forum no one has reported it so maybe I misunderstand the routing flowchart (5.22 of the manual)

To reproduce:

- take a stereo source in a stereo track (for instance, pink noise on the left only for this purpose)

- send it to another stereo track by drag-and-drop

- open the track send control, and change the source to mono 1, and pan the send to hard right

Expected result:

- in the receiving track, I expect to get my source's hard left in the hard right

Instead, I get:

- the source's hard left in the middle of the receiving track, as if the panner did not register the position of the send

Thanks for your help

It's not a bug, it's just the way mono works.
The pan isn't working in this case because there is nothing to pan between, it's only receiving and sending on 1 channel and it needs 2 to work.
To get what you want to achieve send "mono 1" (it's easier to think of it as channel 1) to channel 2.
I can see where you're coming from, and to get what you were expecting then the volume and pan controls would have to come after the destination routing, instead of before (which is the current method).

Thanks so much for this. I'm sorry for the false alarm then. Maybe we should fill a feature request as I think the panner should be between the send source and the receive channels as it is in most other DAWs...

What I don't understand is your second sentence, as I send mono1 to stereo 1-2 (as it says in the window) and I wonder what the panner is used for then (as it seem to work as a balance from stereo to stereo)

What is happening is channel 1 is passed to the volume and pan controls whose output (still only 1 channel remember) is connected to inputs 1/2 of the receiving channel.
I suppose what the other DAWs are doing is taking 2 outputs from the pan.
There was a lot of noise recently from the 1 channel track brigade, and I guess Justin did it this way to appease them.

ok thanks. It is still disturbing as I need to be able to pan each of my send's track... I'll split the file then

Switch the sending track's pan mode to "REAPER 3x Balance"

It works as you'd expect then.

James you are a genius!

Thanks so much. I'm now just worried about the word depredated beside it ;-)

well... The v4 panning is sinusoidal, where as v3 is not.

some info: http://forum.cockos.com/showthread.php?t=49809
(and old old thread before the change)

If you want to stick with the v4 panning you can do a little workaround... (just one way to do it)

insert any plugin, and open up the routing for it. add channels. mult the left input to 3/4... and then have the send come from 3/4 to the recieve.

If you hardly ever use panning automation, v3 is no problem.

Hmm... neither panning mode is ideal really...

v3 panning
issues

"bad" taper
no width or dual pan.

v4 panning
issues

does not affect channels higher than 1/2.
pan law is always 0 for higher channels.
mono sends do not pan as one would expect.

thanks for this again. I'll stick with #3 by ear for now and will study your advanced routing for the future!

Just ran into the same issue as tremblap (currently using Reaper 5.80 x64 on Win7 x64) and I'd say it's definitely a bug: Trying to pan a single-channel receive (choosing input mono source x) is not affected by the send's/receive's pan slider unless one switches the sending track's pan mode to Reaper V3. This is not expected behaviour. One should be able to pan a mono send signal left/right while routing it from a source track to a destination track at least if one chooses -> audio 1/2 (or another stereo pair) as the destination.
